when using mailjet...?

Sorry if this has been asked before. I have done searches and read up on it but am wondering a few things.

I recently downloaded a simple little scraper that pulls emails and such for local businesses. Now let's say I scrape a decent amount say 200 (mailjet per day limit, free) and would like to email them informing them about a service, just asking simply if they would be interested and slap a link to the site in it. Will there be an issue as if that is spam? I want to remain compliant.

Do I need to include an unsubscribe link even though in reality they have never been subscribed to anything?

I know another way of doing this would be to simply call the businesses however I'm pretty aweful when it comes to over the phone or face to face, lol.

Any simple advice would be appreciated, and if I am about to be flamed for asking such a simple question, flame away .
